Photodegradable plastics
 

Photodegradable plastics are plastics that degrade under the action of light.
 

Photodegradable plastics:
 

According to the manufacturing method, photodegradable plastics can be divided into synthetic degradable plastics and additive degradable plastics.
 

Synthetic degradable plastics.
 

Ethylene/carbon monoxide copolymer (E/CO)
 

Photodecomposition is characterized by main chain fracture of biological materials. The photodecomposition rate and degree of E/CO are related to the amount of ketone group in the chain. The higher the content, the faster the decomposition rate, the greater the degree. American scientists carried out outdoor exposure tests on E/CO. In sunny June, E/CO can decompose for a few days at the earliest.
 

Vinyl/vinyl ketone copolymer (Ecolyte)
 

The ketone groups on the side chains of the Ecolyte molecules can be decomposed by natural light. The photodecomposition performance of Ecolyte is better than that of E/CO, but the cost is also high. The disadvantage of these polymers is that they begin to degrade as soon as they are exposed to light. There is almost no induction period and antioxidants need to be added to regulate the induction period.
